[FIX] mrp, sale_mrp: _run_pull creates many pickings

The steps to reproduce:
- Go to a warehouse. Under the technical information tab, change the field sam_loc_id from "WH/Post-Production" to "WH/Stock".
- Create a sales order with 2 different products and confirm it.
- 2 pickings will be created with different group_id MO/XXXX instead of a single picking.

After this commit we only check the sam_loc_id if we are in 3 steps manufacturing.
